Modules of special design with a useful volume of 20 liters and 30 liters are designed for long-term storage and extinguishing with gaseous fire extinguishing agents (GOTV) of class A, B, C fires and electrical equipment under voltage (the voltage at which it is possible to extinguish without turning off the protected equipment must correspond to requirements of NTD for GOTV).
They are used for fire protection of premises and equipment, in a modular design, for volumetric fire extinguishing. Structurally, the modules are metal vessels in the shape of an ellipsoid. There is a metal fastener at the top of the vessels.
In the neck of the vessels there is a shut-off and starting device with an electromechanical stimulator (hereinafter referred to as EMP), a pressure indicator (pressure gauge), a safety membrane and a pressure alarm device (hereinafter referred to as SDS). The module cylinders are painted white.
The modules are not intended for use in hazardous areas.
The modules are manufactured in the “UHL” climatic version, placement category 4 according to GOST 15150, for operation at ambient temperatures from -10 °C to plus 50 °C and relative humidity no more than 80% at a temperature of 15 °C. Package Included:
Modules of special design MGP-20 "SMD" and MGP-30 "SMD" use a locking and starting device (ZPU) from Rotarex, which has three types of triggering:
The manufacturer can make changes to the module design while maintaining its basic operational parameters.
